is there an easy way to wipe cluster tips on NTFS disks if the file belonging to the cluster is locked. i have been using hiedi eraser to wipe my free space but it is unable to process ntuser.dat.log. there is a huge ammount of file slack there that contains data such as newgroups headers and web sites visted. i am trying to find a way to wipe it. i have tried logging in under a differnet account and wiping free space from there, but it doesnt seem to work either.
